I have a function that expects a int * as a parameter. I have an int inside a structure.

Code:
typedef struct myStruct {
  int myStructInt;
} myStruct;


myStruct test_struct;


void test_fun(int * myInt) {
  // yadda yadda
}

int main() {
  test_fun(??????????);
}
How do I pass the address of the structure element? I tried &(test_struct.myStructInt).
